Beschreibung
Zusammenfassung:	An engine assembly having an engine block with at least one cylinder disposed therein, a fuel injector for periodically injecting fuel into the cylinder, a vertically disposed pushrod, a rocker arm disposed for periodic movement and having a first end disposed adjacent the fuel injector and a second end disposed adjacent the pushrod, a camshaft having a cam, and a leaf spring cam follower operatively coupled between the cam and the pushrod. The cam follower has a first portion which supports a cam roller and a second portion which makes contact with the pushrod. The first and second portions of the cam follower, which are spring-biased with respect to each other, may comprise, respectively, a rigid curved member and a flexible, substantially planar member.
